ROLLER-BEARING- Specification of Letters Patent.

Patented April 24, 1906.

To all whom it may concern:

Be it known that I, GEORGE D. SoHEIF- FLER, a citizen of the United States, residin at Jackson, in the county of Jackson an State of Michigan, have invented certain new and useful Im rovements in Roller-Bearings;

and I do here y declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in roller-bearings; and its object is to arrange a series of rollers in a circle equidistant apart and to journal the ends of the rollers in separate rings, which are adjustably connected by'flexible tie-rods or links to form a flexible cage as distinguished from a rigid frame or cage. It has been found that a rigidcage when used with a shaft that does not run quite true'is subjected to a severe strain on account of the irregularity of the surface of.

, the shaft, which tends to crystallize and break the cage. Such cages are thus frequently broken under such conditions.

I have found that by the use of a flexible cage that will 'eld and conform to any slight irre ularity 0 the movement. of the surface of the shaft the rollers will be automatically adjusted parallel to the shaftand will more readily conform to ine ualities in the alinement of such shaft wit out liability of cutting'the bearing-surfaces.

My invention consists, essentially, of a series of rolls provided with conical ends and adapted to surround the shaft, a suitable cylindrical casing or box, rings engaging the conical ends of the rolls and spacing the same apart at regular intervals, and flexible rods connecting the rings and ada ted to hold the same in engagement with t e ends of the rolls, as hereinafter more fully described,-reference being had to the accompanying drawi s, in which i igure 1 is a longitudinal section of a device embodying my invention; 2, a transverse section of the same; I?" 3, a detail in side elevation of the rolls and exlble ca e assembled; Fig. 4-, an end elevation of .t e cage opened to permit the same to be placed on the shaft, and 5 an enla ed detail 0 one of the flexible connecting-r0 s.

ficient internal diameter to Like numerals refer to like parts in all of the figures.

1 re resents the shaft; 2, a suitable cylindrical 0X surrounding the shaft and of sufermit insertion of a series of rolls between t e shaft and the interior of the box; 3, annular heads to the box; 4:, a series of-rolls having a diameter equal to the space between the box and shaft and having conical ends inserted in suitable conical bearings in the opposlngsurfaces of the rings 5. Opposite the axis of each roll are oil-openings 9, extending through the rings to admit oil to the conical ends of the rolls. The rings are also divided at op 0- site sides, as at 8, and connected by su1ta le bolts, preferably by the eyebolts forming part of the connecting means. The rlngs can thus be opened to place the same upon the shaft. Theserings are flexibly connected to each other and adjustabl spaced apart to compensate for the wear 0 the rolls and bearings in the rings by means of eyebolts 7, inserted in the rings and provided with nuts at each side of the rings and connected by rods 6, flexibly connected to the eyebolts, where by the rings are adjustably spaced apart by adjusting the nuts on the eyebolts. The rings are thus free to independently rotate about the shaft to a slight extent and also to move out of axial alinement to a limited extent, whereby the rolls will be free] adapted to any irregularity in the surface 0 the shaft without straining the cage. I have found in ractice that the tendency of this structure is to normally-maintain the rolls in proper alinement with the axis of the shaft and the r' s in axial alinement with each other, and at t e same time the rolls will conform to an slight variation in the surface of the she t from a true cylinder or true alinement with its axis without any injury to the cage and without any binding of the rolls in the case 2.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a roller-bearing, a series of rolls having conical ends, rings having conical bearings for said ends, and rods flexibly connecting the rings.

2. In a roller-bearing, a series of rolls having conical ends, rings having conical bearings for said ends, eyebolts in the rings and consaid rings, nuts carried by said eyebolts and necting-rods flexibly connected to said eye adalgited to abut the inner and outer surfaces bolts. oft e rings and connecting-rods flexibly con- I 5 3.
